immediately before the thread is placed on a run queue they would normally
dwarf the more informative preemption or yield event and it is implicitly
understood that a thread is back on the run queue as part of these events.

- Removed kttcp_sosend() and kttcp_soreceive() in favor of using
sosend() / soreceive() with UIO_NOCOPY. The locking changes in the
socket layer make merging the kttcp_so* and the so* routines a real
pain. It was a lot easier to just use the integrated routines.
- Eliminated KTTCP_MAX_XMIT restrictions on send and receive sizes
because I encountered no problems with streams larger than MAX_INT.
MAX_INT bytes is only good for a few seconds at 4Gb/sec ;)

other until the window is closed. Then one of the sockets is closed, which
will generate a RST once the TCP at the other socket does a window probe.
All versions of FreeBSD prior to 11/26/2004 will ignore this RST into a 0
window, causing the connection (and application) to hang indefinitely.
On patched versions of FreeBSD (and other operating systems), the RST
will be accepted and the program will exit in a few seconds.

Update README to describe the new protocol. The work's broken down into
two main sets of changes.
First, update the existing test programs (shell scripts and C programs)
to produce output in the ok/not ok format, and to, where possible, also
produce a header describing the number of tests that are expected to be
run.
Second, provide the .t files that actually run the tests. In some cases
these are copies of, or very similar too, scripts that already existed.
I've kept the old scripts around so that it's possible to verify that
behaviour under this new system (in terms of whether or not a test fails)
is identical to the behaviour under the old system.

performs a non-blocking connect from another socket, and then closes
the listen socket rather than accepting. This is intended to
exercise the close path in which connections are aborted due to a
close on the listen socket while the connection is in the listen

- Consistently use err/errx/warnx throughout, rather than using perror()
and exit().
- Teach the tests how to better manage (and therefore test) privilege:
in particular, how to create sockes with root credentials but exercise
the privileges with non-root credentials, etc.
- Teach the test suite to apply each of the non-IP_HDRINCL options across
each of SOCK_DGRAM, SOCK_STREAM, and SOCK_RAW.

The IP options section is currently broken but will be fixed shortly.
Not all multicast options are currently tested.

unlike netsend, is to send as many UDP packets as possible; the
cost is that there's no ability to control the rate, and there's
less accuracy in the timing as the interval timer granularity is
relatively low.
1M blocks and optionally write the read data to a file or disk.
If a read error happens, the 1M block gets put on the end of the worklist

If a read error happens again, the 64k block gets put at the end of the

- Centralize time comparison.
- Check clock resolution to make sure it has enough granularity to
implement the desired wait interval.
- Keep track of how many times the timing loop has to spin waiting
for the next send time; report statistics.
- Add commented out warning about deadlines being missed when
spinning.
- Improve statistics reporting generally to provide a more useful
summary of sender condition after a run.

from the gdb(1) register number to offsets within struct reg and
struct fpreg. The tool is useful only on selected platforms. On
ia64 the registers are all over the place to simplify handling of
them in various situations, but which makes creating or maintaining
such an offset table error prone to do by hand.
Since remote kernel debugging operates on the same register numbers,
it would be a natural choice to use an identical offset table in the
kernel. However, since the kernel does not operate on struct reg nor
struct fpreg in the remote gdb(1) case, such would not make sense.
Whether we want to use this tool to create offsets for use in the
kernel or duplicate the knowledge of which register number maps to
what register is something that will become clear soon.
Note: in order to build cross debuggers, one cannot use target
headers and/or target definitions. That's why offsets need to be
hardcoded in the first place. Unpleasant, but necessary.
